Work on the Barton Skyway Ramp Relief Project to relieve traffic along a section of southbound MoPac is scheduled to wrap up this spring, according to an update from the Central Texas Regional Mobility Authority on Jan. 31.

The background

The project began in February 2023 to relieve traffic congestion caused by cars merging onto MoPac from the Bee Caves Road and Barton Skyway onramps, causing delays far beyond that small stretch of road at times, according to CTRMA authorities.

“It’s almost done. We’ve already gotten a lot of great feedback about not only the construction process but the much-needed congestion relief for that snarl in that spot,” Director of Communications Jori Liu said.

The details

The project reconfigures the southbound Barton Skyway and Bee Caves Road ramps, with both entering onto a new through lane on MoPac. According to the CTRMA, the project will add:
  • An auxiliary lane from Barton Skyway to Loop 360 on MoPac South
  • An additional through-traffic lane at Loop 360
  • A left-lane exit-only ramp for southbound Loop 360
  • Room to accelerate for drivers entering from the southbound Barton Skyway on ramp
The project aims to decrease traffic buildup that starts between the Barton Skyway and Bee Caves Road exits.

The impact

CTRMA officials expect this new traffic configuration to ease congestion in the area and allow for more reliable travel times, according to the project’s website. Officials also anticipate the project will improve travel times by up to 40% and serve an additional 770 vehicles during evening rush hours.

What’s next

Most of the project is completed, and final steps are being pursued in the next two months to end the yearlong project, Director of Engineering Mike Sexton said.

“We should wrap up here in spring. It’s going to be weather-dependent, so we can do some asphalt and final striping work,” Sexton said.
